Question about building classification for seismic
(OP)
Hey everyone,
I am designing a concrete moment frame with a steel braced frame on top that holds bulk material (ore). How should I classify this building? Currently I'm analyzing it by taking the total horizontal load from the ore and adding that to the seismic loads of the steel braced frame and concrete moment frame. Also, I'm in seismic zone 3 so I'm not even sure I can use a concrete moment frame also. A sketch is attached FYI. Thanks in advance.

RE: Question about building classification for seismic
Concrete moment frames are allowed in high seismic (at least in US), you just need to meet special detailing requirements.
RE: Question about building classification for seismic
Also, some requirements are required to use the two stages analysis procedure in your design. You can refer 12.2.3.1 and 12.2.3.2 in AISC7-10 for details.
